AUI is the IEEE 802.3 standard name for the cable connecting an Ethernet transceiver (MAU) to a networked device. AUI cables are equipped with a 15-pin connector which mates with a 15-pin connector on the networked device.

Bayonet Neil-Concelman (BNC) connectors were designed for military applications, but are used widely in video and RF applications to 2 GHz. BNC connectors have a slotted outer conductor and a plastic dielectric that causes increasing losses at higher frequencies. BNC connectors are usable above 4 GHz as long as the slots radiate signals; however, these devices may not be mechanically stable to 10 GHz. Both 50Ω and 75Ω BNC connectors are available. BNC connectors are also known as bayonet navy connectors or baby Neil connectors.

FireWire® is a cross-platform implementation of the high-speed serial data bus, defined by IEEE 1394, that can move large amounts of data between computers and peripheral devices. It features simplified cabling, hot swapping, and transfer speeds of up to 400 Mbps. FireWire speeds the movement of multimedia data and large files. It also enables the direct connection of digital consumer products such as digital camcorders, digital videotapes, digital videodisks, set-top boxes, and music systems to personal computers (PC). FireWire is a registered trademark of Apple Computer, Inc.

Gigabit interface converter (GBIC) is a physical component that manages the functions of the FC-0 layer, which determines the physical characteristic of the media and interface, including drivers, transceivers, connectors, and cables.

Subscription channel (SC) connectors are fiber optic connectors with a 2.5 mm ferrule and push-pull latching mechanism. They can be snapped together to form duplex and multi-fiber connectors. The TIA / EIA 568-A standard recommends SC connectors for structured cabling. SC connectors are also used with Ethernet 100Base-FX and 1000Base-LX/SX fiber optic media systems.

Serial port or asynchronous serial interfaces are system-to-system communication interfaces in which data is sent over a single wire (serial). Serial communications include RS232, RS422, and RS485, etc.

ISDN devices must have a terminator (NT1 terminator) between the ISDN device and the wall jack. The U interface connects NT1-terminated ISDN devices to the telephone company's ISDN wall jack. Many ISDN devices have a U interface for direction connection to the wall jack.

Universal serial bus (USB) is a 4-wire, 12-Mbps serial bus for low-to-medium speed peripheral device connections to personal computers (PC), including keyboards, mice, modems, printers, joysticks, audio functions, monitor controls, etc. The USB design is standardized by the USB Implementers Forum (USBIF), an organization that includes leading companies from the computer and electronics industries. The current USB specification is USB 2.0, which supports data transfer rates of up to 480 Mbps.

Restriction of Hazardous Substances (RoHS) is a European Union (EU) directive that requires all manufacturers of electronic and electrical equipment sold in Europe to demonstrate that their products contain only minimal levels of the following hazardous substances: lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyl, and polybrominated diphenyl ether. RoHS will become effective on July 1, 2006.

A virtual private network (VPN) is a connection that has the appearance and many of the advantages of a dedicated link, but occurs over a shared network. Using a technique called tunneling, data packets are transmitted across a public, routed network in a private "tunnel" that simulates a point-to-point connection and allows network protocols to traverse incompatible infrastructures.
